UIL-PUMP FOR CYLINER LUBRlCATION.

SPECIFICATION forming part of Letters Patent No. 722,184, dated March 3, 1903. Applioutinllad April l, 1898. Renewed April 24, 1901. lSerial No. 57,332. (No znodl.)

Be it known-that l, JOHN VJ. MCCLURE, a citizen of the United States, residing at Detroit, in the county of Vtayne, State ofMichigan, have invented certain new and useful Improvements in Oil-Pumps for Cylinder Lu brication; and I do declare the following to he a full, clear, and exact description of the in' ventiori,such as will enable others skilled in the art towhich it appertains to make and use the same, reference being had t'o the aceompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to high-speed oilpumps for cylinder lubrication; and it consists iu the constructionand arrangement of parts hereinafter fullyset forth, and pointed out particularly in the claims.

The objects of the invention are to produce an oil-pump for cylinder lubrication of simple and inexpensive construction which the arrangement is sueltas to provide ior the moet minute-movement of the oil-pump for each turn of theengine, so that in high-speed engines no excess of oil need be fed, out only the requisite quantity to keep the cylinder properly lubricated. y 3

A further. object istoprovide suitable ad justing means to/.regulate the movement of the pump-plunger fOr-eachstrolre of the cran k connected therewith.

A further oh'ject istoprovid fertile ready p from theoil-rservoir for the purpose of c'lea'nf ing or repair."

A further object is to provide a sight-feed through which the passage of the oil 'to the steam-pipegnaybe read-ily seen and in which the arrangement lis ysuchy as to provide for a eirci'ilatiouf otwatei through the'gl'ass', so as to, maintain/the presence of clear .Water at all times within thel feed-glass and lQrevent'the- "accumulation of dirt therein.

These objects are attained by the Emechanism illustratedin the accompanying drawings, in vv'hich- Figure l is a perspective-view of mymproved pump readyforattachrnenttoamoving part of! the engine. Fig. 2 is a vertical transx verse section through "the puinp, its driving mechanism, and the oil-reservoir, the steam- -Iu the to@ of adapted to be closed by a removable plate B.l

Fig. 7 is a sectional view through the holder in the oil-reservoirand the frictiomdisk. lying therein as taken ou line 7 7 of Fig. 9. Fig. 8 is a sectional vieu'l through the'driviug-dislr as taken on line 8 Sof Fig. 9. Fig. 9 isa sectional View as taken on line 9 9 of Fig. 8.

Referring to the letters of reference, A designates the/.bil-reservoir, which is made, preferaoly, of cast-iron and which may he of such size as to carry. the amount of oil required. sa d reservoir is an aperture b,

Attached to and depending from `said plate within the oil-reservoir is the barrel B of the pump, in which the plunger B is adapted to reciprocate vertically, the upper end of said barrel being provided with a suitable stuffing-nox a, closed with a cap a', through which the plunger passes. Attached to the-lower end of the barrel o' the pump is a valve-case C, having a chamber c therein provided Wirl` an intake-port c', controlled by the checkvalve'c. Leading from the chamber c is an oil-passage e, which communicates with a second chamber e', having therein the cheekvalve e",' which controls thevopening leading from said chamber to the passage e. Leading upward from the chamber e' is a pipe d,

whose upper end passes through the plate B and receives a coupling d", in which is located a check-valve d. of the coupling d' is the oil-feed pipe C', which leads to the'steam-pipe C of the engine. (Not shown.) Located in said oil-pipe is the sightfeed. glass D, which enables the engineer to see the amount of oil that is being fedvr to the Attached to the upper end engine. Located in the oil-feed pipe C is s union-coupling j", which enables seid pipe to he uncoupled for purposes hereinafter stated.

lt will now be understood that upon the raising of the plunger oi' the pump the oil in the reservoir will ilow into the chamber c post the valve c". plungerthe oil will 'ne forced out of sztid cheniber und through the pipe (l into the oil-feed pipe C' :ind thence to the steam-pipe ol' the engine. The vertical-l movement of the pumpplunger is effected through the medium of the connecting-rod D, which is jointedly and adjustnhly connected therewith. The jointed attachment ot said connecting-rod to the pump-plunger consists of4 the journal-pinf', to which the upper end of seid rod is jonrneled, as clearly shown in Fig. 2, and which projects horizontally froina coller D", that freely cnihrnces the upper end of seid plunrer and is adopted to move vertically thereon. The adjustable connection between seid rod and seid plunger is obtained through the medium of the adjusting-nuts gend g', which are screwed onto the threaded-upper end ot said plunger and stand on opposite sides of the coller D". Seid coller es itis moved verticnliy through the operation of the connecting-rodD is adopted to successively engage seid adj listing-nuts toimpart s vertical movement to the pump-plunger. It will therefore oe understood that the position of seid nuts with respect to seid collar determines the movement that is imparted to the pumpplunger through the operation of said rod. The upper nog g upon the plunger serves as set-nut to loci: 'the adjusting-nut g' when properly adjusted to impart the requisite movement to the plunger. .It will oe understood that the movement of the plunger determines the quantity of oil which is fed for each stroke thereof, said quantity varying es the plungeris caused to makes long or a. short stroke. i'

The mechanism employed to impart movement to the connecting-rod D is. e frictionel driving mechanism consisting of a frictiondisk E, to which scid rod D is connectedl by ineens of the crank-pin h, nrd the frictionnl driving-disk E-Q'ndnptedtoiartially embrace the disk l?, which disk E is, held inV place'by n. confining-plate E, attached to the face of the oilreservoir. This frictionai driving mechenism is located in n holder F, which consists of a circular recess (see Fig. l5) formed in the fece of the oil-reservoir and termed s fholder, for the reason that it holds and confines the driving mechanism. Back o the recess F end communicating therewith is e. slotted opening F', in which the connecting-rod D'is adapted to play. The friction-disk E is adapted to occupy the innermost recess in the holdervand carries the crank-pin h, which projects into the slotted opening E" end receives the rod D', which is jonrrialed thereon. This disk E is provided troni-.1v rsely oi, its periphery Wit-l1 e series of Then upon the descentof seidgine.

recess recesses L, foi-ined by cutting right-angled slots in the periphery of seid'dislr, producing recesses, earch of which has e. redinl side, es shown. These recesses cre occupied. by two series of rollers 71.' and h, lying side by side. Esch of these rollers is engaged by seperate spring i', sented in. the dininetrice-l fece o' seid recess sind hearingr against seid rollers, respectively. The inner series of these rollers confined in recess in said disk by means of the annuler shoulder lt, formed. in the holder F, the dieineter of the opening ol' seid holder Within said annuler shoulder v'oeingr such is to snugly receive seid disk lil, es clearly shown in Fig. 7, so that seid inner series of rollers in seid recess is normally held by springs against the fece of said shoulder end the tangent plone of seid recess7 whereby seid disk is locked within seid holder against Imy backward movement or a. 'rotaryrmovement to the left7 es such movement would conse seid rollers to wedge hetweenthe shoulder 7c. of the holder and the tangent face of said recess-Ll thereby arresting; scid disk. The outer series of rollers h withiuth'e recesses of said disk is adopted to engage the inner face of the annuler flange le', 'projecting let,- emlly from the frictional driving-disk E', which is adapted to freely lie Within the outer ennnlofr opening of the holder end embrace the outer edge ol the disk E, so es to conlineA the series of rollers 7i within the recesses seid disk E, which rollers, by ineens of the springs which heer against them, are norinally held in contact with said flange llt' of the disk E' and the tangent pinne of 'the recess of the disk E. Seid disk E is adepied to rotate and is provided with e. raised central portion or heb m, which projects through. e centr-il opening in the plete it", that is secured to the fece of the oil-reservoir and serves to retain the diei; E in place, although permitting seid dislf; to rotete. Movement is imparted to the dist: E' through the medium of the bnr G, which is attached to the rsieed. central portion thereof Afind is provided et its outer end with e suitable coupling G', adepted. for attachment to a. moving part of the en- (Not shown.) A reciprocating motion imparted to the outer end o' the ber will cause the drivinff-dislr E' to oscillare which 9 movement will impart on intermittent rotary motion to the frictionel disk E end e consequent movement of the connecting-rod D and of the plunger of the pump. ln the oscille.,- tion of the disk E the disk E kis driven only during the movement of the disk E to the right, which movement wedges the outer eerieso rollers 7i between the flange k of the driving-dist'. and the tangent plone ofthe recesses i, causing the disk E to turn to the right with the disk A olivi/ord movenient of the disk E or e movement to the' `disk E end permitting the disk E to move freely 'tothe left, While the dist: E renininr.

The driving-disk E' by its oscillation imparts an intermittent rotary motion to the disk E. The operation of this frictional driving mecl1- anism is so perfect that the most minute m ove in en t .of .the.di-.Luingry dis lrasimpaetcd-te the disk E to cause it to gradually turn to the right, so that the mere'st vibration of the outer end of the lever Gr is imparted to the disk E in the form of an intermittent rotary movement to the right, thereby operating the connecting-rod and driving the pump. The arrangement of parts is such as torenable the attachment of the voperating-rod G t0 the movable part of an eng-ine running at the highest speed, and yet impart but the requisite number or" strokes to the pump, owing to the very`in-inute movement which may be imparted to the disk E through av movement of-the-conuecting-bar G, and by further adjustment, made possible by the Ireservoir at the proper state oi fluidity a steam-pipe o is passed and returned through the casting H at the bottom of thereservoir. The presence ot' steam in said pipe tends to heat the contentsv of the reservoir to the proper temperature. l

The sight-feed D, located in the oil-feed pipe C', leading from the pump to the steampipe, comprises a coupling H-, having at each end the smiling-boxes Hffgwhich receive and conne the ends ofthe'iglass Liuto the lower end of which the oil-feednozzle 7' yprojects. The oil leaves the end of said nozzle r ina drop ,and passing upward through the glass f and at its lower end fcommunicates with .a

passage ls, leadin,r into the sight.- feed at-vali point below the lower end of the glass there? in, as clearly shown in Fig. 3. `The condensation of steam within said pipe .l will cause" the sight-feed glass to lill with Water, which stands in said glass `and in the oil-feed pipe ing-pipe will fill with water to a poilt on a line with the entrance to the oil-feed pipe into the steam-pipe C (see Fig. 2) and thatafurvtheracoumnlation of lwater in the condensing-pipe will cause alike amount of water to flow out of said oil-pipe into said'steam-pipe,

the feed-glass, which insures the presenceof clear water in the glass atall times and obviates the accumulation of dirt therein.
